The 5:2 Diet Thread number 18! Breaking out the summer wardrobe?

998 replies

GreenEggsAndNichts · 22/04/2013 10:51

The continuing thread for those of us following either the 5:2 diet or the alternate-day fasting diet.

The 5:2 diet was featured on Horizon in August 2012, and essentially requires you to fast for 2 non-consecutive days per week. The other 5 days, you can eat what you like, or approximately your TDEE (see explanation below). Alternate-day fasting is just how it sounds; you fast every other day. By "fasting", we mean that we keep our calorie consumption very low, around 500 calories on average for a woman, 600 for a man, on those days.

You'll find on these threads we use a number of acronyms. If you're new to the threads, or Mumsnet in general, they might not make much sense.

WOE/WOL = Way Of Eating/Way Of Life. We use this term instead of "diet" as many of us see this as something to do in the long term.

MFP = My Fitness Pal, a website many use for keeping track of the number of calories they're eating.

TDEE = Total Daily Energy Expenditure, quantifies the number of calories you burn in a day. This measure is best estimated by scaling your Basal Metabolic Rate to your level of activity. TDEE is critical in tailoring your nutrition plan to desired fitness goals. Here is a link to a calculator to help you figure out how many calories you should be eating in a day.

ADF = Alternate-day Fasting, as it says on the tin, fasting every other day rather than 5:2.

Michael Mosley has recently unveiled a new website to accompany his new book on the subject. Please go check them out, as he's the whole reason most of us are here!

I know a number of people lurk on this thread, as this is currently quite popular. Please just jump in and post if you're new- you'll find a lot of support here.

Here is a list of links to get you started with this way of eating. Please let us know if you find a new article or some other information online:

First things first, here are links to some of our previous threads: most recent one before that another one!

Another thread which breadandwine has started is a good resource for some of the links and tips that get lost in these big threads. In addition to sharing links, we try to condense some of our top tips for fasting there. Keep in mind, we all do this differently, so these are just tips, not rules. This might be a good place to catch up with us if you're feeling a bit lost!

frenchfancy has a recipe thread over here, please post any low-calorie recipes there so they don't get lost in these bigger threads!

If you've been at this a while and are moving on to maintaining your goal weight, there is a thread here to discuss that.

Here is the link to the BBC article regarding Michael Mosley's findings, which was featured on Horizon.

There's a link to the aforementioned Horizon programme here.

A blog post here gives some of the scientific explanation for why this way of eating helps you to not only lose weight, but improve your all-around health.

A Telegraph article which comments on the diet and gives a brief overview by Dr Mosley himself, very informative if you're just starting. (I highly recommend this for an overview)

A study discussed here gives commentary specifically addressing the effect of this diet on obese people (both men and women), with regard to both health and weight loss. ("After 8 weeks of treatment, participants had an average 12.5 lbs reduction in body weight and a 4 cm decrease in waist circumference. Total fat mass declined by about 12 lbs while lean body mass remained relatively constant.) it also mentions "Plasma adiponectin, a protein hormone that is elevated in obesity and associated with heart disease, dropped by 30%. As did LDL cholesterol (25%) and triglycerides (32%).")

Something to consider if you are currently your ideal BMI: this appears to suggest the benefits for women at a lower BMI might not be seeing the same health benefits that are found on men at their ideal BMI.

A BIG THANK YOU to all who have been contributing, btw. Most of us are learning this way of eating as we go along. All of the links above have been posted by others in our previous threads, and they've been very helpful. Sorry if I haven't given credit where it's due, but it was just enough of a job getting all the links re-copied and back into one post.

Come join us, and tell us about your experiences with this diet!

ginger thanks for that, it's really inspiring :) I had gestational diabetes and really don't want to end up with type 2 so good to know it helps the blood sugar too :)

So far today fasting has been really easy [confusing] I had a slice of toast and a snack pot of beans at 3.30. Need to have dinner soon (omelette with mushroom and onion) but have already reached my 24 hour mark.

On a separate note DD is really grizzly and is driving me mad!!!

stickygingerbread · 01/05/2013 19:22

There is a health event at the office next week where cholesterol will be tested. I hope to update at that time.
Thank you, the posters who have shared advice on leg cramps. In the past I had only suffered leg cramp when pregnant, but definitely it has become more frequent since taking up fasting. I take a calcium, magnesium, zinc supplement, and drink more water at first sign of cramp. This seems to work.
Since starting on this and seeing such changes, I have become motivated and interested in looking into other information on maximizing nutrition and have recently been introduced to traditional foods movement. We live in an area well served with farmers who are practicing these farming techniques (and training apprentice farmers) in this intellectual movement and who run buying clubs. Medium term I am planning to join a buying club for milk, eggs, and meat. The price would be more, but we are eating less. I have also become even more interested in new cooking and recipes - find myself meal planning on fast days!

stickygingerbread · 01/05/2013 19:26

Dotty342kids yes! I was in despair over losing weight. It would. not. go. Feel like I've learned some key secret about the body.

stickygingerbread · 01/05/2013 19:34

MeNeedShoes I was borderline for gestational diabetes and came in just the right side of the line in the 3-hour glucose test with dc2. Later developed preeclampsia. In retrospect that may have been related to what must have been chronic high insulin. On the good side, I did manage to have 2 dc with undiagnosed pcos.
It was with dc1 that I gained all the weight - it was very dramatic and fast (another symptom of pcos). Neither gained nor lost with dc2.
But yes what I learned from the books (in addition to 5:2, the Alternate Day Diet by James Johnson, and Blood Sugar Solution by Mark Hyman were very informative) is how insulin drives weight gain and also contributes to long term health problems like heart disease and stroke. Both my grandmothers had heart disease and one a stroke. [hmmm]
I should probably mention that my high motivation for improvement and nutrition comes from the drive to TTC a dc3 before the fertility window shuts. If I succeed, I will put the fasting to the side for the duration and focus on the high nutrition low-glycemic load eating.

LexingtonBear · 01/05/2013 19:39

Mmmm - for a work day evening meal on a fast day when I've no time to cook - m&s delicious and nutritious range Harissa salmon and tabbouleh is v yummy and only 345 cals. I had to have an emergency skinny flat white this morning as my eyes just wouldn't open at work (!) so I broke my fast earlier than id have liked but thereapart this is all I've had and I feel great. Fingers crossed my tummy's floodgates of hunger don't open now! Hmm, that sounds a bit of a graphic description - didn't quite mean it like that!

Hope others have done well today

BsshBossh · 01/05/2013 19:43

stickygingerbread what an inspirational series of posts. Well done. Are you at goal weight now?

stickygingerbread · 01/05/2013 20:00

Bssh ultimately I would like to be around 8 stone 10. I am a small-boned 5'4", and before pg my highest weight was 8 stone 8. Seems a lifetime away from recent years. So about half way there.
But if the loss slowed now it wouldn't bother me as I fit in to the few remaining pre-baby clothes I kept. Oh and I just this weighing crossed over into top of normal bmi range.

DorisShutt congratulations on resisting the pudding. Huge psychological victory!

Sariah · 01/05/2013 20:08

4th fast today. Finding it ok. Haven't weighed myself at all but reckon I will know if I am losing weight. I cycle 25km on week days so that should help too. Not counting on the normal days and sticking to 500 on my fast days. Sugar is my weakness. Had 2 apples today, prawn salad and salmon and veg. Huge prawn salad for 130 cal in m&s it was a crunchy citrus salad and took ages to finish.

peplum41 · 01/05/2013 20:10

Evening allSmile

Came to the threads feeling a bit wobbley, as in its been one of those eat, eat eat days. Plus Ive put a couple of 1lbs on, and I don't think they're the bouncy kind because clothes felt a bit tighter today. So going to tend to some 5:2 admin and reset my TDEE and start logging on MFP. Went for a really long uphill walk to offset calories but then came home and resumed foraging for cheese and chocolate, then suddenly realised I was thirsty. When will I learn?? Drink the water first!

Anyway, the reason Im rambling on, is that I realised as I was scrolling through the posts that I had that calm, full feeling again, without the urge to stuff a cake in it. So thanks fellow IFers for your support, and keep posting.

Congrats to eliza for your little granddaughter. Smile

Welcome to the new posters, as usual so many, hope you find the threads as motivating as me.

stickygingerbread (yum) I love stats posts, especially the extra glucose readings and waist measurements, thanks for that. Well done. I have PCOS, so yes with you on that. Im also appleshaped, so it doesn't usually go from the waist, usually the legs which are skinny anyway, but Ive noticed its going from the waist with fasting. Its fascinating the effect it has on insulin etc, which is what keeps me motivated to have long fasting time zones, at least 16 hours either side of the 500 cals.

akarucker · 01/05/2013 20:17

My watch is loose!! Small victories Smile

Doilooklikeatourist · 01/05/2013 20:19

I managed really well today .
DesperateDietingHousewife
I'm making myself the family a lovely cake tomorrow ,
MeNeedShoes I need a fast buddy !
I'm thinking we all do that's why there's all the chat on here !
My deadlines are a Silver Wedding Party ( my DH was Best Man ) late May bank holiday , and we are going on a holiday this year .
No pressure !

Dotty342kids · 01/05/2013 20:20

My weight is definitely going from the middle (I'm apple shaped too) too. Which is just fab as I hate the large, bloaty feeling!

Salbertina · 01/05/2013 20:24

Hello shall join you all tomorrow

ElizaCBennett · 01/05/2013 20:33

My 36 hour fast is going ok so far, only had tea today and will not eat now until the morning. Really hoping for a weight loss in the morning, if so I will do 36 hour fasts from now on.

swallowedAfly · 01/05/2013 20:39

no don't worry! yesterday was my fast day and i just happen to not eat in the day anyway so normal not to eat till after work for me and that doesn't change following a fast. so a 36hr fast automatically becomes a 40 odd hour one because of the way i eat.

no tomorrow isn't a fast day but my point was that i hope by doing a total fast day, followed by a pretty calorie light day come tomorrow my appetite will be a bit controlled as i won't be used to eating loads so a nfd won't turn into a pig out day i hope.

sorry - don't worry i'm not trying to starve myself or anything.

swallowedAfly · 01/05/2013 20:42

i'm also hoping that i could somehow do a total fast one day followed by a 500cal day the next as all of my fasting for a week. i find it easier to not eat at all and not feel hungry the next day so manage 500 than i do to try and do two separate days so i'm hoping that might be the way forward for me. basically like those who do consecutive days but i'll do day one as a total fast and day two as a 500 day if i can do it. a nice long total fast and both days gone in one block rather than building up momentum twice. bear in mind Dr M did four days or something and intermittent is just designed to make it easier except i'm now wondering if it does make it easier or i'd be better off biting the bullet for a big one once a week. itms.

DesperateDietingHousewife · 01/05/2013 20:54

stickygingerbread very interesting reading, thank you. I'm starting to realise that it's a good thing this diet has come along-def think I would have gone the same way as my dad and brother with type 2 diabetes. I was also tested for the gestational type but luckily it was negative.

The insulin thing-they call it "syndrome X" is that right?-I think I would probably have ended up done that road too-if I wasn't already there. My tummy measurement is huge-I literally look about 5 months pregnant but have got good at holding it in!

Was feeling hungry around 3.30-I find that time difficult but had a can of Waitrose carrot and coriander soup (90 cals) and starving again about 5.30pm. The hunger went about 6pm and I did wonder if I should just forget about having dinner but as I'd already cooked it, I didn't want to waste it (Waitrose spinach and ricotta cannelloni (245 cals) and had a few chopped strawberries) but after I'd eaten it, I started to feel really hungry. I have got a rumbling tummy now, but I'm going to go to bed. Have a spa day tomorrow with two friends so I will enjoy my eating day but as I'm not in the house (and with friends), I won't be bingeing like I did yesterday.

doilooklikeatourist enjoy your cake tomorrowSmile...even typing that has made me drool!

Sunshine78 · 01/05/2013 21:08

Stickygingerbread, I am you! also had 2 DC with undiagnosed pcos just been diagnosed doafter a bit of research thought I would give 5_2 a go reading your posts tonight while feeling abut hungry from my 2nd fd you have inspired me to keep up and not let in after all I can eat tomorrow!

stickygingerbread · 01/05/2013 22:08

Drat it, I had a big post responding to all recent posts but was logged out while drafting it. Now I've run out of time & must go. Will try to respond more fully later but I am so glad to know the info/experience I posted is helpful & resonating with similar experiences. I hope that all of us doing 5:2 and IF for health benefits also will share their experiences (and data!) on that front.

tomorrowweeat · 01/05/2013 22:50

Bad day :(

fatsatsuma · 01/05/2013 22:52

Can I de-lurk to ask a question please? I love these threads but haven't posted before.

I've been doing 5:2 for about 7 weeks and have lost 7lbs which I'm happy with. Currently 10:4 but would like to be nearer 9:8.
I haven't found fast days very hard but have really struggled with feeling cold this week. I know this is a recognised side affect but can anyone encourage me that it's actually a good sign?? It's coincided with a slight bounce (only 1lb but still) so I'd love someone to say that feeling cold preceded a really good weight loss
Grin

EATmum · 01/05/2013 23:39

Just saying hello (waves) as someone new to 5:2. Just finished my second fast, and staggered that it hasn't been hard, as someone who thinks about (and eats) food A LOT. I actually got hungrier yesterday when I was eating normally. Shows how much of my "hunger" is in the mind - when I switch it off, it really doesn't impact so much.

Although I did find sleeping the first night tricky - partly because I (TMI) woke up needing to pee (too many cups of herbal tea) and then found I was hungry and thinking about food - probably because the end was in sight?

Any tips for managing nights better? Please don't say "don't drink coffee" because that will make me cry (and I really don't have more than 1 or 2 a day ...)

wonderingagain · 01/05/2013 23:48

I'm fairly sure the feeling cold is a physiological change to do with dieting, perhaps it means that the body is starting to use up fat stores instead of what's in the gut. Not sure really but I would love to know the answer.

Here's an interesting sciency article if you're interested.

Tortoiseontheeggshell · 02/05/2013 01:00

Stickygingerbread, I had gestational diabetes with both my girls, despite being very low risk; it's actually fortunate that over here in Australia they test everyone irrespective of risk, because I was 29, with a BMI of 23, and no family history of diabetes, and yet I had it. So I consider myself 'pre-diabetic' now, which has been a large part of wanting to start this diet, so it's really, really good to read your stats, thank you!

Tomorrow is a fast day, DH and I are going to the supermarket today to pick up some ingredients to get us through. I want miso soup, right? Green tea? Anything else you guys rely on that you'd like to recommend?
